DISCLOSURE OF THE INVENTION

The problem which the present invention is intended to solve is that theclosing means must be operated to open the opening portion whilepreventing the dropping out of the housed article because the openingportion of the aforementioned housing bag is closed with the closingmeans with the result that there arises a disadvantage in that the usercannot swiftly take out the housed article. In addition, an attachmentwork for attaching the closing means onto the opening portion must beadded to the manufacturing process.

An object of the present invention is to provide a housing bag whichsolves the aforementioned problem with the result that the housing bag,does not require any closing means, facilitate the handling by the userand the manufacture thereof while preventing the dropping out of thehoused article and the widening of the opening portion.

In order to solve the aforementioned problem, the housing bag accordingto the present invention has an internal configuration which isapproximately the same as an external configuration of an article to behoused therein, and a bag-like configuration having an opening at oneside thereof; the bag being characterized by comprising:

a cushion material; and

an auxiliary material having an elasticity, a stability and an endurancehigher than the cushion material and the material constituting the mainportion of the bag;

wherein the cushion material and auxiliary material are arranged in anoverlapping manner on the internal circumference of the opening portionalong the internal circumference thereof with the result that theopening portion is formed in a thick manner with an elasticity.

Incidentally, preferably, the aforementioned auxiliary material is athermo-plastic urethane resin-made sheet.

According to the present invention, it is possible to realize a housingbag wherein the opening portion is formed of a cushion material in athick manner instead of providing the closing means for closing theopening portion, so that the housed article is pressed to the internalcircumference of the opening portion to prevent an easy dropping out ofthe housed article and the taking out of the housed article isfacilitated.

Furthermore, an auxiliary material with a high elasticity, stability andendurance is used together with the cushion material with the resultthat it is possible to prevent the widening of the opening portion andan easy dropping out of the housed article.

BEST MODE OF EMBODYING THE INVENTION

In FIG. 1( a), symbol A shows a housing bag according to the presentinvention. This housing bag A is intended to house and protect aportable game device and the housing bag A is constituted in such amanner that taking in and out of the housed article is facilitated, andeasy dropping out of the housed portable game device is prevented and itis easily taken out.

A main body 1 of the bag which constitutes the housing bag A is providedwith a surface processing with polyurethane in order to protect a cloth(Tetron cotton) from stains, moisture or the like, and the bag is formedin such a manner that the width W1 is approximately the same as thethickness W2 of the article to be housed and the depth L1 is madeapproximately the same as the height L2 of the housed article so thatthe internal configuration of the bag is made approximately the same asthe external configuration of the article. The main body thereof isformed in an approximately rectangular bag-like configuration having anopen one end. On an internal circumference of the opening portion 2, asshown in FIG. 1( b), a cushion material 3 is provided. The openingportion 2 is formed in a thick manner with the cushion material 3 tonarrow the opening portion 2. The dropping out of the housed article isprevented without providing any closing means such as a string, abutton, a fastener or the like while an auxiliary material 4 with a highelasticity, stability and endurance is arranged on an internalcircumference of the cushion material 3. According to the presentinvention, urethane is used as the aforementioned cushion material 3,and a thermo-plastic urethane resin is used as the auxiliary material 4.

In this housing bag A, as shown in FIG. 2( a), a tape-like auxiliarymaterial 4 is overlapped at both end portions in the longitudinaldirection of the rear surface 5 a of the cloth 5 constituting the mainbody 1 of the bag. After overlapping a belt-like cushion material 3thereon, the surface 5 b of both end portions is folded back to the sideof the rear surface 5 a respectively so as to wrap the cushion material4 and the auxiliary material 3, and the cushion material 3 and theauxiliary material 4 are housed in the folded back portion 6 bystitching the cushion material 3 and the auxiliary material 4 togetherwith the folded back portion 6 along the “a line” so that a thickportion 7 is formed. Thereafter, as shown in FIG. 2( c), the cloth 5 isfolded at the center thereof so that the rear surface 5 a is directedtoward the outside so that the main body thereof is formed in a bag-likeconfiguration by stitching both side portions and the lower portion ofthe cloth 5 along the “b line” and the “c line” respectively (see FIG.2( d)). As shown in FIG. 2( e), when the cloth 5 is folded back, thefolded back portion 6 is located at the inner side of the openingportion 2 with the result that the housing bag A can be formed which hasan opening portion 2 provided with a thick portion 7.

Incidentally, when both end portions of the cloth 5 are stitched alongthe “b line”, it is preferable that the portions be stitched in thestate in which the auxiliary material 4 is extended to some extent. As aconsequence, when the auxiliary material 4 is restored after thestitching, the inner circumference of the opening portion 2 can be madesomewhat smaller than the external circumference of the housed article.

The housing bag A which is formed as described above is such that thedepth L1 is made approximately the same as the height L2 of the housedarticle B and the width W1 is made approximately the same as thethickness W2 of the housed article B with the result that theconfiguration of the inside is made approximately in the sameconfiguration as the housed article. (see FIGS. 3( a) and (b).

In housing the article B to be housed in the aforementioned housing bagA, as shown in FIG. 3( a), the article B to be housed is pressed intothe bag from the opening portion 2. At the time of actually pressing thearticle B to be housed into the opening portion 2, as shown in FIG. 3(b), the article B is pressed into the bag by pressing the thick portion7 toward a right-wise and a left-wise direction. As shown in FIG. 3( c),in the state in which the article B to be housed is housed in thehousing bag A, the depth L1 of the housing bag A is approximately thesame as the height of the article B to be housed with the result thatthe upper portion of the article B to be housed corresponds to the thickportion 7 of the opening portion 2. Since the internal circumferencesurface of the opening portion 2 is made thick, the opening portion 2 issandwiched by this thick portion 7 with the result that the article B tobe housed is pressed by the thick portion 7 so that dropping out of thearticle B to be housed from the opening 2 is made difficult.

As shown in FIG. 4( a), when this article B to be housed is taken out ofthe housing bag A, as shown in FIG. 4( b), pressing the bottom of thehousing bag A from below results in the pressing out of the housedarticle B from the opening portion 2 with the result that the projectedportion of the article B is pinched and pulled out from the housing bag.Thus, the housed article can be easily taken out without the operationof opening of the opening portion such as unraveling of the string,detaching of the button, opening of the fastener or the like.

At the time of taking in or out of the housed article B, the openingportion 2 is forcibly widened with the result that there is apossibility that the closing state of the opening portion 2 is notmaintained by reason that the cushion material 3 has gone slack bytaking in and out of the housed article B repeatedly. However, theauxiliary material 4 which is soft like rubber and which is formed ofstrong thermo-plastic urethane resin such as plastics and metalmaintains the state of the opening portion 2. Consequently, a housingbag A can be realized which is capable of maintaining the closed stateof the opening 2 forever by recovering the expansion and slack of thecushion material 3 and which is capable of preventing the dropping outof the housed article B without using a closing means such as a buttonand a fastener for closing the opening portion while being capable oftaking out the housed article B without operating the closing means, thebag being effective both for the manufacturer side and for the userside.
